Success!

On the advice of the good people on this forum, I upgraded to firmware 3.0 on my 2G iPod Touch - I ended up paying for it through iTunes, as iTunes refused to recognise the ipsw file I'd downloaded. After that, though, redsn0w 7.2 was totally easy - and now it all works beautifully! I'm having a lot of fun playing with themes and little system gadgets live LiveClock. Such fun!

Soon I'll experiment with using it under linux, with gtkpod instead of iTunes.
